To all whom it may concern: I

Be it known that 1, CHARLES BEA-neon, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Tandem Draft Connections for Mowing-Machines, of which the following is a specification.

My invention relates to mowing machines,

chine having my invention forming a part thereof;

Fig. 2 is a side elevation, partly in section, of Fig. 1; r

Fig. 3 is a detached detail of part of the main frame of the machine and the steering mechanism;

Fig. 4; is aside elevation of part of the steering wheel mechanism; and

Fig. 5 is a diagrammatic view showing two mowers connected in tandem relation by means of my, device.

The same reference numerals designate like parts throughout the several views.

1 represents the main frame of the ma chine, mounted upon carrying wheels 2, and having thereon arising and fallmg coupling frame 2 of the usual construction, and, as

shown, the rear end of a stub draft tongue 3 secured thereto, this stub tongue being disposed abovethe coupling frame. 4 repre sents a supplemental draft member having the rear end thereof pivotally connected with the frame of the machine and likewise disposed above the coupling frame, and 5wrepresents a caster wheel mechanism supporting the front end of the stub tongue. 6 represents a vertically arranged shaftjournaled in the stub tongue member 3, having a sprocket wheel 7 secured to the upper end' thereof and an arm 8 to its lowerend, the

almbeing connected with the supplemental draft member l by means of a link 9.

1 0 represents a draft bracket member secured to the rear end of the main frame 1, and 11 a vertically arranged support secured to member 10- and having a shaft 12 journaled therein. Secured to the lower end of the shaft is a sprocket wheel 13 smaller than the sprocket wheel 7,. and 14- represents a chain connection between the sprocket wheels 7 and 13. 15 represents a locking lever mounted upon the bracket member 10 and yieldingly held in engagement with the sprocket wheel 13- by means of a spring 16, that permits the lever tobe depressed by the o-perators foot in a manner, to" disengage the lever from the sprocket member 13 and permit the operator to turn the shaft 12 in its bearings by means of the hand wheel 17 secured to the upper end of the shaft. The mechanism. is designed for use in connection with a: series of mowing machines when drawn. in. tandem relation by means of a traction engine; the supplemental draft member of one of the machines being connected with the draw bar of an engine, and other supplemental draft tongues connected with thebracket members 10. Obviously the operators may manipulate the hand wheels in a manner to vary the line of draft of each machine independent of the others by varying the angular relation of stub tongue and thesupplemental draft members as shown by dotted: lines in Fig. 1. l 7

It will be noted that in my improved construction, through theprovision of the braki-ng mechanismincluding the member 115 under the control of theoperator, the draft tongue 5 may be maintained in any desired positionof adjustment, the pressure of. the member 15 against the sprocket 1 3 being sufficient to' prevent rotation of the latter and a consequent movement of the pole. It is also to be noted that through the provision of this'mecha'nism the operator may at any time permit the pole to swing freely so thatit may be adjusted by the draft, the operator, when such an adjustment is desired, simply pressing down the member 15,. whereupon the sprocket 18 and its connected: sprocket may rotate freely and the pole may be moved by the=draft. Attention is also directed to the fact that in my improved construction a three-wheeled truck is provided which is entirely independent of the cutter mechanism, thelatter being free to rise machines of the series having their and fall and accommodate itself to uneven ground without in any way interfering with the draft mechanism which extendsout over I the same, the stub tongue 3 of this draft mechanism being fixed to the frame, wlnle the draft tongue 4, though permitted a lateral movement, is also maintained against a vertical movement which would cause it to v. conflict with the rising and falling coupling frame. V

While I have in this application specificallyl described one embodiment which my invention may assume in practice, it; is to be understood that the form shown herein is used for purposes of-illustrationand that V the invention may be modified and-assume various other forms without departingfrom its .spi'rit,1it being my intention to.include all such modifications within the scope ofthe appended claims. 7 I a What I claim. as my invention, and desire to secure by Letters Patent, is

.1. In a tandem draft attachment, a'frame,

' sprocket carried by said shaft, a crank arm 5 carried by said shaftyconnections between j tongue; and a chain connection, between said sprockets whereby upon movement-of said said crank and said laterally swinging second sprocket and crank said tongue'is adjusted.

3; Ina tandem draft connection, a frame, a laterally swinging tongue operativelyconnected to said frame,a link connection between the. same and said frame, and meansfor swinging said link connection and thereby 'swinging said tongue including a .plurali'ty of horizontally disposed sprockets and V a' chain connecting the same.

4. In a tandem draft connectlon, a frame,

' a stub tongue fixed to said frame, a later ally swinging tongue fixed against vertical movement and pivotally connected to'said frame and disposed at one side of and substantiallv parallel to said stub tongue, and

' laterally swinging tongue operativelycon= .means for adjusting said laterally swinging tongue relative to said stub tongues;

. 5. In a tandem draft attachment, a frame, a

nected. thereto, means for adjusting said tongue including a rotatable member and a link connection between said tongue and frame operable by said rotatable member, and a movable braking member carried on said frame and engaging said rotatable member.

6. In a tandem draft attachment, a frame, a laterally swinging tongue operatively connected thereto, means for adjusting said tongue including a rotatable member and a link connection between said tongue and frame, and a movable resiliently mounted foot lever normally engaging said rotatable member.

7. A tandem draft connection for mowers including, in combination, a main frame, a draft tongue member secured to said main frame,'a supplemental draft tongue having the rear end thereof pivotally connected with said mainframe, a draft bracket secured to the rear side of said main frame, a vertically arranged shaft journaled in said fixed draft tongue, an arm secured to the lower end of said shaft, a link connection between said arm and said supplemental draft member, a gear member secured to the upper end of said shaft, and gear mechanism carried by said main frame and operative to turn said gear wheel in opposite directions. 1

8'. A tandem draft connection for mowers including, in combination, a main frame, a

Y draft tongue member secured to said main frame, a supplemental draft tongue having the rear end thereof pivotally connected with said main frame, a draft bracket secured to the rear side of said main frame, a vertically arranged shaft j ournaled on said fixed draft tongue, an arm secpred to the lower'end of said shaft, a link connection between said arm and said supplemental draft member, a gear member secured to the upper end of said shaft, gear mechanism carried by said main frame and operative to turn said gear wheel in opposite directions, and means for locking said gear mechanism in various positions'of adjustment.

9.
